Optical Schematic of the Laser Particle Counter

OPERATION THEORY
Utilizing the principle of "near angle light scatter", a revolving laser beam passes through the walls of a glass container of a flow-thru cell. When it is directed through a central "sensitive zone" the PC-2200 not only counts the particles in suspension, but tabulates their size as well. The analog signals generated by the light pulses are routed to a computer and digitized.

CALIBRATION
Spectrex provides three sealed calibration standards with each unit. Each standard contains a precise number of NIST traceable polystyrene spheres of known size in suspension and are sealed with inert Argon gas. These standards have a proven stability of more than 10 years and provide efficient calibration within 10 minutes.

SuperCount SOFTWARE
Developed by Spectrex, the custom interfacing electronics and proprietary software provide an easy means of analyzing and saving data generated by the PC-2200. SuperCount provides instant sizing information and histogram of size distribution in addition to indicating:

  • Absolute Counts
  • Mean Size
  • Mass Distribution
  • Percentage Distribution
  • Standard Deviation
  • Total Suspended Solids

The dilution factor can be automatically computed to give absolute count for liquids as dense as sludge! SuperCount also is loaded with a special bonus program for hydraulic fluids* and Phi classifications.

OPTIONS

  • Opacity Meter - provides an instantaneous measurement of the sample's opacity to correlate with computer calculations.
  • Small Vial Attachment - For use with 5ml vials or ampules.
  • Magnetic Stirrer - built into the PC-2200 when ordered, eliminates selting by inducing a constant motion of the sample.
  • Flow-Thru Cell - Spectrex stocks various sizes of flow-thru cells and can manufacture cells to customer specifications. Cells are also available for testing at high pressure and temperatures.
